16 This target is used for running U-Boot on top of Coreboot. In
17 this case Coreboot does the early inititalisation, and U-Boot
18 takes over once the RAM, video and CPU are fully running.
19 U-Boot is loaded as a fallback payload from Coreboot, in
20 Coreboot terminology. This method was used for the Chromebook

26 This is the Chromebook Pixel released in 2013. It uses an Intel
27 i5 Ivybridge which is a die-shrink of Sandybridge, with 4GB of
28 SDRAM. It has a Panther Point platform controller hub, PCIe
29 WiFi and Bluetooth. It also includes a 720p webcam, USB SD
30 reader, microphone and speakers, display port and 32GB SATA
31 solid state drive. There is a Chrome OS EC connected on LPC,

41 Intel Platform Controller Hub EG20T, other system components and
42 peripheral connectors for PCIe/SATA/USB/LAN/SD/UART/Audio/LVDS.

154 bool "Platform requires Intel Management Engine"
156 Newer higher-end devices have an Intel Management Engine (ME)
157 which is a very large binary blob (typically 1.5MB) which is
158 required for the platform to work. This enforces a particular
159 SPI flash format. You will need to supply the me.bin file in
160 your board directory.
163 bool "Perform a simple RAM test after SDRAM initialisation"
165 If there is something wrong with SDRAM then the platform will
166 often crash within U-Boot or the kernel. This option enables a
167 very simple RAM test that quickly checks whether the SDRAM seems
168 to work correctly. It is not exhaustive but can save time by
169 detecting obvious failures.
